Effect of organophosphorus pesticide application on hot pepper yield land its parameters)-Capsicum annuum L,. cv. Ancho San Luis

We studied the effects of the commercial products Gusation 35 PH(R), Parati on CE720(R) y Tamaron 600 LM(R), and an active ingredient without mixtures (metamidofos) on pepper (Capsicum annuum L. cv. Ancho San Luis) yield and y ield components. Four doses were used: the one recommended on the label of the product; half, 1.5 times and twice the recommended dose. Three frequenc ies of application (once and twice a week, and once every 15 d) were tried, for six weeks, from the beginning of flowering. Yield (RE) and yield compo nents (weight of fruit [PF] and fruit size [TFI]), and both flowering (DFL) and fruiting dynamics (DFR) were the parameters. The results showed that t he improper application of insecticides may develop toxicity, finally impin ging on harvest results.
